| 摘 要： | 如何经济、科学地确定最少空测采样飞行起落次数，并能保证实测载荷参数数据的可比性与再现性，是目前国内外在编制飞机载荷谱时十分关注的问题。根据ｔ分布理论，按照一定置信度和误差要求，给出了确定飞机最少空测采样飞行起落次数的设计准则，以此作为现场实施空测采样的依据。

| Abstract: | During on the spot measurement of airplane loading spectra, it is an annoying problem how to determine the flight takeoff landing number of minimum no loading measurement sampling economically and scientifically ensuring the typical representativity, science, comparability and revealability of actual measurement loading data above the confidence level of 90% in compiling airplane loading spectra home and abroad so far. According to t distribution theory, this paper proposes a criterion and estimation equations of the confidence level of normal mean population by which the flight takeoff landing number of minimum no loading measurement can be defined under a certain confidence level and error limit so that the flight takeoff landing number of minimum no loading measurement sampling can be determined. |
